ELECTRIC HEATER.

, To all whom it my camera:

Be it known that I, LESLIE E. A. KELSO, a citizen'of the United Statesof America, and resident of Olmsted Station, Provo, in the county ofUtah and State of Utah, have invented certain new and usefulImprovements in. Electric Heaters, of which the following is aspecification.

My invention relates to an electric heater operated by an electriccurrent passing through water.

The object of the invention is to provide a construction whereby theheat will be automatically regulated. p

In a general way, the conception comprises electrodes immersed inanelectrolyte, and means for causing the quantity of water between theelectrodes to vary inversely as the consequent heat, thereby.maintaininga practically constant temperature, the water being the most-appropriateand convenient kind of electrolyte to be employed.

The figure of drawing is a partly vertical sectionof the structure, someportions be ing shown externally.

At A is a steam dome, consisting of a vessel with its r'nouthdippinginto water B, which is held in a second vessel C, closed to the outsideatmosphere by the cover D which connects the upper rim of the vessel Cto the outside walls of the vessel A, for providing an air space E abovethe water. The vessel A does not rest on the bottom of the vessel B butis raised slightly for the purpose of permitting the water to floweither from the vessel A to the vessel C or vice versa. The plate D alsoforms the support for holding the vessel A at the right height.

F represents insulators for supporting electrodes G within the waterinside of the Walls of the vessel A.

The operation is as follows;-When an electric current is passed throughthe water Specification of Letters Zatent. "Patented Feb.20, 1912.Application filed April 12, 1911. Serial No. 620,836.

from one ofthe electrodes to the other, the

Water is heated and the usual results oca the reverse operation ensuesif heat is abstracted from the steam. dome, for the pressure thenbecomes less, and more Water comes from the vessel C to the vessel A.

The numerous uses ofrthe heater need not be mentioned. As an instance,it may be said that the whole device may be submerged in water or otherli uids for raising their temperature' To adjust the device, more watermay be put in by removing the cap H. a

I claim as my invention In an electric heater, the combination of avessel, water therein, a second and inverted vessel dipping into saidwater by which position a steam containing-dome is formed above a partof the'water which is directly below the said second vessel, a cover Dconnecting the up or rim of the first named vessel to the outside wallsof the second named vessel for providing an air space above the waterwhich is outside of the inverted vessel, the inverted vessel beingmaintained elevated above the bottom of the first vessel for the purposeof permitting the water to flow from either vessel to the other undervariations of steam pressure in said dome, and electrodes-immersed inthe'water which is directly under said dome.
